CARDlNG-MACHINE.-

SPECIFICATION forming part of Letters Patent No. 443,415, dated December23, 1890. Application filed November 8, 1881. Serial No. 254,619. (Nomodel.)

To all whom it may concern:

Be it known that 1, JOHN P. THOMPSON, of Fall River, in the county ofBristol and State of Massachusetts, have invented certain new and usefulImprovements in Carding-Machines, of which the following is a full,clear, and exact description,reference being had to the accompanyingdrawings, forming part of this specification.

This invention relates to acarding machine or engine for opening andstraightening out cotton, wool, or other fiber.

The object of my invention is to provide what may be termed a doublecard, which w1ll prove an efficient and economical machine. To theaforesaid purposes my invention, brlefly stated, consists, essentially,in having the licker-in, the carrier-cylinder, and doiferroll arrangedin the stated order intermediate the lap-roll and the main cylinder, inhaving a set of feed-rolls posterior to the lap-supply roll and a set offeed-rolls anterior to the main cylinder, in having the vibrating packerco-operating with the doffer-roll and the doffer and the feed-rollsposterior thereto, in having the traveling conveying-apron for conveyingthe lap partly through the machine, and in the construction of thevibrating packer and the vibrating doffer.

In order that my invention may be fully understood, I have illustratedin the accompanying drawings and will proceed to describe the best formsthereof so far devisedby me, with the knowledge, however, that suchforms admit of modifications.

In the accompanying drawings, Figure 1 is a side view of my improvedcarding-machine, shown with part of the main cylinder and framingomitted. Fig. 2 is an enlarged side view of a portion of the machineshown in Fig. 1, and shows the drive-shaft and the rockshaft with thedoffer and the packer and the intermediateconnections. Fig. 3 is a frontview of the part shown in Fig. 2. Fig. 4 is a horizontal sectional viewof the parts shown in Fig. 2, the section being taken on line 4 4 ofFig. 2. Fig. 5 is an enlarged side view of a part of the machine shownin Fig. 1, with some of the side framing removed and showin g moreclearly the endless conveying-apron under the packer. Fig. 6 is anenlarged detached view of the packer, with the rock-shaft and the loosesleeve of the packer shown in cross-section. Fig. 7 is a sectional viewof the packer, taken on line 7 7 in Fig. 6, viewed in the direction ofthe arrow therein shown, and shows the toothed packer-blades in advanceof the toothless blade. The blades in this viewhave central sectionsshown as broken away. Fig. 8 is a sectional view of the packer, taken online 8 8 in. Fig. 6, and shows the toothless packer-blade broken away atthe center. Fig. 9 is a view of another form of packer, the view beingsimilar to that shown in Fig. 6. Fig. 10 is a sectional view of thepacker, taken on line 10 10 in Fig. 9. Fig. 11 is a side view of stillanother form of packer. Fig. 12 is an enlarged view in detail of aportion of the packer plate or blade shown in Figs. 9 and lO, with apacker finger or tooth mounted therein.

In the said drawings like numbers of reference design ate correspondingparts thro u ghout.

Referring to the drawings, the number 3 designates the ordinarymachine-framing, at the right-hand end of which is mounted thelap-supply roll 30, which supplies the fiber to the feed-rolls 31, and32 is the licker-in, ithe carrier-cylinder, and 5 is the doffer-roll,from whence the lap passes through the feed-rolls 16 to the maincylinder The aforesaid card-cylinders are provided with the usualcard-clothing and are mounted to turn in their hearings in a manner wellknown. Likewise the feed-rolls 31 and 16 are rotary rolls of theordinary construct-ion, which may have one of each set given a positivemotion in the usual manner.

My invention consists in part in the disposition or relativearrangementof these several old devices, together with the novel features,

which I will now proceed to describe.

Near the doiter-roll 5, to the left thereof in the view shown in Fig. 1,the drive-shaft 11 is mounted in the bracket 35, formed with the recess37, and the shaft is provided with the end of which has a bearing (notshown) on the other side of the machine, and this shaftis provided withthe fixed rocker-arm .l, by means of which the shaft may be rocked inits bearings indirectly by the drive shaft 11 through means of theeccentric 30, formed on the drive-shaft and the eccentric-rod 10,0011-necting the eccentric with the rocker-arm 9 by the pivot 38. l'pon therock-shaft '7 is rigidly secured a pair of arms 39, only one of which isshown, the omitted one being located upon the opposite side of themachine from the one shown, and these arms carry the ordinarydofter-comb ti, which is given a vib 'atory motion by means of therock-shaft and acts to strip the fieece from the dol'ten roll 5 in theordinary manner.

My novel packer 1T strikes upon and packs and presses the fleece into asheet after the same is stripped from the doFter-roll by thedofter-comb, and is given a vibratory motion by the shaft 11 similar tothe motion which is given to the dofter-comb by means of the rock-shaft7. The packer consists in a sleeve 18, mounted loosely 011 therock-shaft 7 and provided with the internal bearing-ridges 19, andhaving the packer-arms 20 cast thereon and each formed at the end withthe eye 4:0 to receive thebolt ll for attaching to the arms the packerblades or plates 21, which are provided with the packer teeth or fingers22. The sleeve 18 has a rocking motion imparted to it by the drive-shaft11, so as to vibrate the packer through the following means: To thesleeve is rigidly secured by the screw t3 the bent rock-arm l2, whichprojects ovcrinto the recess 37 of bracket 35, and to the end of whichis pivoted by means of the pin it the eccentric-bar to, which isconnected by its other end to the eccentric 36.

The packer teeth orfingersfli? maybe formed integral with the blades, orthey may be separate pieces inserted in the blades, as shown in Figs. 9,10, and 1:3, wherein the tooth 22 is a cylindrical plug having a forkedor notched lower end it i In the construction of the packer shown inFigs. 0, 7, and and the preceding figures there are used a set oftoothed blades, together with one toothless blade, and these blades areformed with perforations to receive the bolts and are arranged apart andparallel with the spacing-pieces t7 thcrebetween. In

the forms shown in Fi s. 9 and 11 there is i C) only one blade 21 used,which in the former instance is provided with teeth 22, latterconstruction is a toothless fiat blade L-shaped in transverse section,

Beneath the packer and doffcr is disposed my improved conveying-apront8, disposed between the (letter-roll 5 and the feed-rolls 16. Thisapron is endless and is mounted on the rolls 49, any one of which may begiven a positive rotary motion in a suitable way, so asto keep the apronin constant motion in the direction from the dolfenroll toward theteed-rolls 16.

and in the In Fig. 5 a lanai-pulley is shown in broken lines secured toone end of the lower feed-roll 10, and a similar band-pulley is shownsecured to the end of the shaft of the roll 4ft immediately under thepacker. These two band-pulleys are shown connected with adriving-bant'l, thus imparting motion to the belt t8, delivering thepacked fiber to the iced-rolls it at the same speed at which thefeedrolls deliver the fiber to the carding-cyliuder.

In the operation of the card the cotton-bat passes from the lap-roll 30through the feedrolls 3i, whence it is taken by the licker-in 32 and theearrier-cylimler i to the doft'er-roll 5 to open the lap and partiallyclean and straighten the fibcr, which is stripped from roll 5 by the(letter-comb G, and, coming under the blows of the packer 17, is packedand thence carried by the apron is to the feedrolls 1G, whence it passesto the main cylinder 233.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. In a cardingenginc, the combination, with the maincarding-cylinder,of the following sncccssivcly-operatin ginstrnmentalities: a lap-supporting roll, a pair of feed-rolls, alicker-in, a carrylug-cylinder, a doffer-roll and dofiTer-comb, acarrying-apron, a fiber-packing device, and a pair of Eecd-rolls, allconstructed to feed the lap to the licker-in, carry the fiber from thelicker-in to the (letter-roll, doff the fiber, pack the dotted fiber,and feed the packed fiber to the main carding-cylinder, as described.

2. The combination, in a carding-engine, with the feed-rolls and thelicker-in, of a carryingcy1inder, a dotting-cylinder and doll.-ing-coinb, a packing mechanism, an endless apron for conveying thepacked fiber, and a pair of feed-rolls constructed to feed the opened,doffed, and packed fiber to the main ardingcylinder, as described.

3. The combination, in a carding-engine with the main cylinder and apair of feedrolls adapted to feed the fiber directly to the maincylinder, of mechanism for preparing the fiber, consisting of a pair offeed-rolls for feeding the lap to the licker-in, alieker-in for openingthe lap, a carrying-cylinder, and a dottcr-roll for carrying andcondensing the fiber, provided with a dotfer-comb, a reciprocatingpacker mechanism, and acarryingapron, all constructed to open the lap,partially straighten and clean the fiber, collect, condense, and packthe fiber, and deliver the packed fiber to the feed-rolls adjacent themain cylinder, as described.
